【発明の詳細な説明】 〔産業上の利用分野〕 本発明は，自動車電話端末装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an automobile telephone terminal device.
従来，自動車電話端末装置では，自動車電話端末装置ご
とに識別コード（IDコード，例えば，電話番号）が一つ
割り当てられており，該当識別コードに対応する回線を
用いて通話を行っている。Conventionally, in a car telephone terminal device, one identification code (ID code, for example, a telephone number) is assigned to each car telephone terminal device, and a call is made using a line corresponding to the corresponding identification code.
上述のように従来の自動車電話端末装置では，一台につ
き一つの識別コードを備えているのみであり，複数の回
線を使用するには回線数に応じた台数の自動車電話端末
装置を所有する必要がある。As described above, the conventional car telephone terminal device is provided with only one identification code per device, and in order to use a plurality of lines, it is necessary to own a number of car telephone terminal devices according to the number of lines. There is.
従って，一台の電話端末装置のみを所有する場合には，
一回線しか使用できず，例えば昼間と夜間で公用と私用
に電話端末装置を使い分ける等の利用方法ができない。Therefore, if you own only one telephone terminal,
Only one line can be used, and it is not possible to use the telephone terminal device for daytime and nighttime for different purposes.
本発明の目的は実質的に複数の回線を使用できる自動車
用端末装置を提供することにある。It is an object of the present invention to provide an automobile terminal device that can use a plurality of lines substantially.
本発明によれば，識別コードによって通話制御を行う制
御部を備える自動車電話端末装置において，時刻を計測

記制御部は前記時刻情報によって現時刻を認識し，該認
識時刻に対応して前記選択回路を制御して，前記識別コ
ードを選択制御するようにしたことを特徴とする自動車
電話端末装置が得られる。According to the present invention, in a car telephone terminal device including a control unit that controls a call by an identification code, a clock circuit unit that measures time and sends it as time information, a memory that stores a plurality of different identification codes, A selection circuit for selecting the identification code and giving it to the control unit, wherein the control unit recognizes the present time based on the time information, controls the selection circuit according to the recognition time, and performs the identification. An automobile telephone terminal device characterized in that the code is selectively controlled can be obtained.
次に本発明について実施例によって説明する。 Next, the present invention will be described with reference to examples.
第１図を参照して，時計回路１によって時刻が計測さ
れ，時刻情報として中央処理（CPU）２に与えられる。
そして,CPU2はこの時刻情報によって現在の時刻（現時
刻）を認識する。Referring to FIG. 1, the time is measured by the clock circuit 1 and given to the central processing unit (CPU) 2 as time information.
Then, the CPU 2 recognizes the current time (current time) based on this time information.
メモリ４には第１のメモリ番地4aに第１の識別コードID
（ａ）が格納され，第２のメモリ番地4bに第２の識別コ
ードID（ｂ）が格納されている。そして，メモリ４はス
イッチ選択回路３を介してCPU2に接続されている。The memory 4 has the first identification code ID at the first memory address 4a.
(A) is stored, and the second identification code ID (b) is stored in the second memory address 4b. The memory 4 is connected to the CPU 2 via the switch selection circuit 3.
CPU2には予め切換え時刻が第１の切換時刻コード及び第
２の切換時刻コードとして設定されており，上述の時刻
情報が第１の切換時刻コードとなると,CPU2はスイッチ
選択回路３に第１の制御信号を与える。これによって，
スイッチ選択回路３は第１の識別コードID（ａ）を選択
し，この第１の識別コードID（ａ）がCPU2に与えられ
る。The switching time is preset in the CPU2 as the first switching time code and the second switching time code. When the above-mentioned time information becomes the first switching time code, the CPU2 causes the switch selection circuit 3 to switch the first switching time code to the first switching time code. Give a control signal. by this,
The switch selection circuit 3 selects the first identification code ID (a), and this first identification code ID (a) is given to the CPU 2.
つまり，電話端末装置は第１の識別コードID（ａ）で通
話を行うことになる。That is, the telephone terminal device makes a call using the first identification code ID (a).
一方，時刻情報が第２の切換時刻コードになると,CPU2
はスイッチ選択回路３に第２の制御信号を与える。これ
によって，スイッチ選択回路３は第２の識別コードID
（ｂ）を選択し，この第２の識別コードID（ｂ）がCPU2
に与えられる。つまり，電話端末装置は第２の識別コー
ドID（ｂ）で通話を行うことになる。On the other hand, when the time information becomes the second switching time code, the CPU2
Applies a second control signal to the switch selection circuit 3. As a result, the switch selection circuit 3 has the second identification code ID.
Select (b), and the second identification code ID (b) is CPU2
Given to. That is, the telephone terminal device makes a call using the second identification code ID (b).
上述のように時刻に応じて，識別コードを変えるように
したから，一台の電話端末装置で実質的に２回線を使用
することができる。Since the identification code is changed according to the time as described above, one telephone terminal device can substantially use two lines.
上述の実施例では２種類の識別コードを備える場合につ
いて説明したが,3種類以上の識別コードを備える場合に
も同様に適用できる。In the above-described embodiment, the case where two types of identification codes are provided has been described, but the same applies to the case where three or more types of identification codes are provided.
以上説明したように本発明では，複数の識別コードを備
え，時刻によって識別コードを切換えて使用しているか
ら，一台の電話端末装置で実質的に複数の回線を時間帯
別に使い分けることができ，例えば昼間の公用電話器と
夜間の私用電話器の使い分けを回線加入料のみを回線数
分だけ支払うだけで可能とし，複数回線の利用を経済的
にも物理的にも容易に実現できるという効果がある。As described above, according to the present invention, since a plurality of identification codes are provided and the identification codes are switched depending on time, one telephone terminal device can substantially use a plurality of lines according to time zones. , For example, it is possible to use public telephones during the daytime and private telephones during the night separately by paying only the line subscription fee for the number of lines, and it is possible to easily use multiple lines economically and physically. effective.
